iPhone 4 Announced

Apple has unveiled its new iPhone 4 after a couple wild, unprecedented months of leaks. Sure, it looks exactly like we expected it to (Steve compares it to an old Leica camera), with a glass front and back, but it’s what’s on the inside that counts, kids. The stainless steel band that goes around the phone is an antenna system, while also providing the main structure of the phone, though it’s plugged into the same old GSM / UMTS radio you all know and love — there’s a reason they didn’t call it the iPhone 4G. There’s also of course that front facing camera we were all anticipating, a rear camera with LED flash, and a new high resolution display that doubles the pixels in each direction (960 x 640) for a 4X overall pixel count increase — Apple calls it a “Retina Display.” It’s rated at 326ppi, which Apple claims is beyond the human eye’s limit of distinction. Check out an example of the new screen up against the iPhone 3G after the break. Similar to the iPad it’s an IPS display, with 800:1 contrast. Naturally, it’s still the same old 3.5-inch. Under the hood is the A4 processor that runs the iPad. Despite the new engine (and the 25% thinner chassis), Apple managed to make the battery slightly larger, and the new handset is rated at 7 hours of 3G talk, 6 hours of 3G browsing, 10 hours of WiFi browsing, 10 hours of video, and 40 hours of music. Oh, and that WiFi? It’s 802.11n now. The camera has been bumped to 5 megapixels, with 5X digital zoom and a “backside illuminated sensor,” which now can also record HD video at 720p / 30fps.

On the software front, applications will automatically get high resolution text and buttons, and with “a little bit of work” developers can make their entire app compatible with the new resolution display. Developers will also get access to a new gyroscope, giving devs “six axis” motion control between the gyroscope, accelerometer, and compass, with a new “Core Motion” API to deal with it all. Users won’t be left out in the cold, however: they can mess around with that new HD video using a brand new iMovie app. Developing…
